the knowledge guide function, wherein all frameworks, the management of knowledge are all managed by the information management center with maintenance, knowledge edition and modification are convenient in organization of unity.The user double-clicks the framework that will edit on the view at information management center, can edit this framework on editing view.The data of knowledge editor 12 flow to knowledge compilation device 17 by the I/O access module.Frame inference machine 13 is a kind of data structures, the characteristics of this data structure maximum are can description object and relation between objects, framework is made up of groove, the frame inference machine is mainly finished the evaluate operation to frame slot, and this evaluate operation is that the inherited attribute according to the taxonomical hierarchy structure of frame system and frame slot defines and finishes.The data of frame inference machine 13 are transmitted mutually by data bus and top control module 18.The rule of rule-based reasoning machine 14 is a kind of knowledge representation forms, and its use will be finished by the rule-based reasoning machine.What rule-based reasoning machine 14 used is a kind of forward reasoning method, forward reasoning (also claiming data-driven) is from known argument, utilize and the true rule that is complementary, carry out the new fact of expansion, this process carry out repeatedly until reach to set the goal or rule can be by coupling till.The data of rule-based reasoning machine 14 are transmitted mutually by data bus and top control module 18.Method inference machine 15 is a kind of procedural languages, can the implementation procedure operation, numerical evaluation, reasoning control and message transmission.This process was divided into for two steps: the one, and the search of method and coupling, another is the execution of procedure body.When a piece of news was sent to target framework, the method inference machine must at first extract all method that is had in this framework, then these methods and message is complementary, and obtains the method that is complementary with message, the coupling of method that Here it is.The data of method inference machine 15 are transmitted mutually by data bus and top control module 18.Interpreter 16 is finished the explanatory note of each scheme reasoning process, the purpose of interpreter is to use the process of the clear more understanding decision-making in family, the correctness that judgement is found the solution, enhancing is to gained result's degree of belief, and the data of interpreter 16 are transmitted mutually by data bus and top control module 18.The effect of knowledge compilation device 17 is with text mode knowledge compilation to be become the knowledge organization form of internal system, is stored in knowledge memory 19 with the form of binary file.Domain knowledge storer 21 provides knowwhy, common sense knowledge and experimental knowledge, the data message of domain knowledge storer 21 flows to knowledge memory 19 by the I/O access module, knowledge memory 19 is deposited knowwhy, common sense knowledge and experimental knowledge, knowledge memory 19 is to gather knowledge, put in order, abstract and formalization (title knowledge acquisition), with the receptible form of computing machine (the title representation of knowledge) these knowledge are left in the knowledge memory 19 then, the management of knowledge memory 19 is finished by knowledge editor 17, and the data of knowledge memory 19 flow to top control module 18 by the I/O access module.Top control module 18 is invoked procedures between each inference machine of control, and each inference machine is for the reasoning solicit operation of top control module.Top control module 18 will be finished field data and keep when calling, so that can recover the reentry point of upper level reasoning when end is called in reasoning, continue the reasoning operation of last layer.It is the knowledge system development environment of an opening that data-carrier store interface 22 can make native system, can dock with other data-carrier stores.The data of data-carrier store interface 22 flow to context data memory 20 and figure support programs interface 23 by the I/O access module respectively, figure support programs interface 23 is laid a good foundation for continuing follow-up works such as design, can call various large-scale graphics software bags.The data of figure support programs interface 23 flow to context data memory 20 by the I/O access module.Context data memory 20 is dynamic knowledge, the fact knowledges that produced by system dynamics, it and data-carrier store are similar, reflect dynamically or deposit the raw data and the fact when finding the solution field question, and centre and object information, context data memory 20 is by data bus and top control module 18 mutual swap datas.
As shown in Figure 4, the workflow of howitzer design proposal reasoning arithmetic element is: step 37 is an initial actuating for to set up task according to tactics index, according to the technical indicator that requires in the charter, selects reasoning task.Step 38 is for to determine the design feature parameter according to technical requirement, and according to technical requirement, reasoning provides the primary structure characteristic number of howitzer conceptual design.Step 39 provides the primary structure characteristic number by inference for to choose tentative programme from knowledge memory, chooses original scheme from scheme standard memory and knowledge memory, and revises the formation tentative programme.Step 40 becomes new departure for the reasoning of input driving parameters, and the tentative programme to forming drives according to primary structure characteristic number that provides and bullet design driven constraint condition storer, forms new departure.Step 41 is carried out the calculating of the architectural feature number of bullet for carrying out projectile structure characteristic number accurate Calculation.Step 42 is calculated for carrying out bullet intensity, stability, trajectory, according to equation and formula, intensity, flight stability and the trajectory of bullet is comprehensively calculated.Step 43 is that various result of calculations are detected assessment for assessment, if assessment is defective, then enter in the step 44, step 44 is for entering Change In Design, setting up new departure, according to design change package, and the scheme of making amendment once more, set up new departure, turn back to step 38 again,, then enter step 45 if assessment is qualified, design finishes, data deposit storer in, and then the reasoning design finishes.
